Locate the small brackets along the side of the white center block that hold the red, yellow, black, and white wires in place.

With your fingers, gently pull the wires away from the center block so that they are no longer held up by the brackets.

Flip the white center block over so that the black speaker is facing upwards.

Firmly grasp the speaker with your hands and pull it up and away from the center block until it fully disconnects from it.

The speaker is attached to the center block via the 4 metal slots along its edges.
